JOHN GOETTEL, OF BOSTON, MASSACHUSETTS.

TRUCK FOR ELECTRIC CARS.

SPECIFICATION forming part of Letters Patent No. 636,980, dated November14., 1899.

Application filed April 18, l 8 9 9.

and it consists in combining with the frame-' work of an electric cartruck a base-piece adapted to form the seat for the central springs andalso the support or foundation for an electric motor, the objects beingto make a cheap, efficient, and durable device for connecting the motorto the truck and axle and to avoid I shock and undue strain on theparts. These objects I attain by means of the mechanism shown in theaccompanying drawings, in which- Figure 1 is a plan showing atruck-frame made up entirely of iron and having a motor supported by myimproved device. Fig. 2 is a vertical longitudinal section showing apart of the truck-frame and the motor-support and motor. Fig. 3 is avertical longitudinal section showing parts of the frame, the motorbeing shown in elevation.

The truck-frame illustrated is of the kind known as the Goettel diamondtruck and need not be fully described in this specification. Attentionis called to my Patent No. 348,459,dated August 81, 1886, foracar-truck.

A represents a part of the frame of a carbody, and B the transom-bolt. AA represent a transom-block firmly connected to the carbody and throughwhich the transom-bolt passes. A spring or springs are placed at S andrest upon the base-piece M, Fig. 2, or, in a modification shown in Fig.3, a basepiece E.

The framework of the truck is composed mainly of wrought-iron bars, asfollows: LL L L are longitudinal bars connected at their ends to theaxle-housings and centrally to cross-bars C O G O. The upper cross-barsO O are connected by bolts D D to the transom-block A A and thecorresponding lower cross-bars O O to the base-plate M, Fig. 2, or, inthe modification, to the base-plate E. The truck-frame also haslongitudinal bars L which are connected to the ends of the Serial No.713,485. (No model.)

cross-bars C O. The base-piece M rests upon springs S S, one at each ofthe bolts D D. Short cross-bars I. L Fig. 1, give additional strength tothe frame, all of the parts of which are firmly bolted together, asshown.

The wheels W W and the axles W W are of ordinary construction.

The internal construction of the motor is of any of the improved stylesand has the ordinary transmitting-gears for connecting itsarmature-shaft to the ordinary axle of the car.

The motor-suspension devices and the combination of the same with thetruck-frame constitute the noveltyin this application and will now beset forth.

The base-piece M is integral with the lower part of the outer casing ofthe motor-that is, M M represent a single casting or, possibly,

forging. P and P are sets of arms extending from the motor-case M andserve as supports for the axle-bearings R R and the springs T T. Bolts PFig. 1, provided with nuts and checknuts, serve to hold theaxle-bearings in place. By the above-described device the motor will beheld securely to the axle and still have a yielding bearing, so as toavoid injury to the motor from violent shocks that the Wheels mayreceive in rapid running. The part M, already referred to as thebase-piece, is

supported on springs S S, so that the motor is also elasticallysupported at its rear end. The upper part M of the motor-casingis madein the usual manner for this class of motors and need not be described.

In Fig. 3 the motor-support E E is made in dependently of themotor-casing, the casing being bolted or otherwise attached to it. Thisform of motor-support may be connected to the axle W, as shown in Fig. 3or as shown in Fig. 2.

I claim- 1. In a truck for electric cars, a metallic framework atransom-block and a spring between said transom-block and a base-pieceand said base-piece which serves as a footpiece for the said spring orsprings and forms an integral part of the motor-support, and alsoextending to the axle and having bearings resting upon said axle,substantially as and for the purpose set forth.

2. In a truck for electric cars, a metallic framework, a transom-blockand a spring or springs between said transom-block and a name to thisspecification, in the presence of base-piece, and said piece which formsa suptwo subscribing witnesses, on this 25th day 10 port for the motorand extends to the axle of March, A. D. 1899.

and has bearings resting upon said axle; and

5 springs under said base-piece and resting JOHN GOETTEL' upon theframework, substantially as and for Witnesses: the purpose set forth.FRANK G. PARKER,

In testimony whereof I have signed my H. O. CLAPP.
